ben wedeman is in gaza city. frederick pleitgen is in ashkelon city. we begin with sara sidner at the scene of that bus explosion that happened just a little while ago in tel aviv. sara first of all describe for me how that looks right now. >> what has happened right now is the cleanup is under way. there are still tape up around the scene. we're very close to the defense department building, and the military headquarters, this is a bus that the number 61 bus, we know that it exploded, glass all around the bus was blown out. however the blast was not strong enough to knock out the ability for the bus to operate. and so we saw literally the bus -- someone in the bus drive the bus away, 15, 20 minutes ago. we know that there are several people injured. they were taken to a hospital. that is very, very nearby where this bus exploded. right now, police are telling us that they are still looking for potential suspects, we see a helicopter in the sky. there's been a lot of confusion, a lot of rumors, as to who may have done this. even rumors about an arrest.
